SUMMARY

Embodiments of the present invention relate to an enantiomericallypurified agonist of the G-protein coupled estrogen receptor (GPER),pharmaceutical compositions comprising an enantiomerically purified SRRG-1, or a derivative thereof, and methods of treating disease states andconditions in subjects in need thereof, and methods of treating diseasestates and conditions mediated through GPER receptors.

Estrogens mediate multiple complex physiological responses throughoutthe body. The responses are in turn mediated through the binding ofestrogen to receptors. The classical receptors bind steroids, such asestrogen, and are soluble cytoplasmic/nuclear proteins that function astranscription factors. These receptors are known as estrogen receptoralpha and beta (two closely related proteins) that mediatetranscriptional activity. GPER is a 7-transmembrane G protein-coupledreceptor that also binds to estrogen with high affinity (K_(d) ^(˜)6 nM)and mediates rapid cellular responses including cyclic adenosinemonophosphate signaling, calcium mobilization and phosphatidylinositol3,4,5 trisphosphate production.

Diseases whose development, progression, and or response to therapy, maybe influenced by endogenous, and/or pharmacologic activation of GPERsignaling include cancer (including the prevention of cancer, preventionof the reoccurrence of cancer, and the inhibition of the progression ofcancer; and particularly melanoma, pancreatic, lymphomas, uvealmelanoma, non-small cell lung cancer, breast, reproductive and otherhormone-dependent cancers, leukemia, colon cancer, prostate, bladdercancer), reproductive (genito-urological) including endometritis,prostatitis, polycystic ovarian syndrome, bladder control,hormone-related disorders, hearing disorders, cardiovascular conditionsincluding hot flashes and profuse sweating, hypertension, stroke,obesity, diabetes, osteoporosis, hematologic diseases, vascular diseasesor conditions such as venous thrombosis, atherosclerosis, among numerousothers and disorders of the central and peripheral nervous system,including depression, insomnia, anxiety, neuropathy, multiple sclerosis,neurodegenerative disorders such as Parkinson's disease and Alzheimer'sdisease, as well as inflammatory bowel disease, Crohn's disease, coeliac(celiac) disease and related disorders of the intestine.

It must also be noted that as used herein and in the appended claims,the singular forms “a,” “an,” and “the” include plural reference unlessthe context clearly dictates otherwise.

As used herein, the term “about” means plus or minus 20% of thenumerical value of the number with which it is being used. Therefore,about 50% means in the range of 40%-60%.

In embodiments or claims where the term “comprising” is used as thetransition phrase, such embodiments can also be envisioned withreplacement of the term “comprising” with the terms “consisting of” or“consisting essentially of.”

As used herein, the term “consists of” or “consisting of” means that thecompound, composition, formulation or the method includes only theelements, steps, or ingredients specifically recited in the particularclaimed embodiment or claim.

As used herein, the term “consisting essentially of” or “consistsessentially of” means that the compound, composition, formulation or themethod includes only the elements, steps or ingredients specificallyrecited in the particular claimed embodiment or claim and may optionallyinclude additional elements, steps or ingredients that do not materiallyaffect the basic and novel characteristics of the particular embodimentor claim. For example, the only active ingredient(s) in the formulationor method that treats the specified condition (e.g., cancer and/orobesity) is the specifically recited therapeutic(s) in the particularembodiment or claim.

As used herein, the term “a derivative thereof” refers to any molecularform of the compound it references, including, but not limited to, asalt thereof, a pharmaceutically acceptable salt thereof, an esterthereof, a free base thereof, a solvate thereof, a hydrate thereof, anN-oxide thereof, a clathrate thereof, a prodrug thereof, an isotopethereof (e.g., tritium, deuterium), a co-crystal thereof, and anycombination of the foregoing.

Asymmetric centers exist in the compounds disclosed herein. Thesecenters are designated by the symbols “R” or “S,” depending on theconfiguration of substituents around the chiral carbon atom. It shouldbe understood that the invention encompasses all stereochemical isomericforms, including diastereomeric, enantiomeric, and epimeric forms, andmixtures thereof. Individual stereoisomers of compounds can be preparedsynthetically from commercially available starting materials whichcontain chiral centers or by preparation of mixtures of enantiomericproducts followed by separation such as conversion to a mixture ofdiastereomers followed by separation or recrystallization,chromatographic techniques, direct separation of enantiomers on chiralchromatographic columns, or any other appropriate method known in theart. Starting compounds of particular stereochemistry are eithercommercially available or can be made and resolved by techniques knownin the art. Additionally, the compounds disclosed herein may exist asgeometric isomers.

Where A and B are the respective mole fractions of the enantiomers in amixture such that A+B=1. A racemic mixture has an enantiomeric excess of0%, while a single completely pure enantiomer has an enantiomeric excessof 100%. As an example, a sample with 70% of R isomer and 30% of S willhave an enantiomeric excess of 40%. This can also be thought of as amixture of 40% pure R with 60% of a racemic mixture (which contributes30% R and 30% S to the overall composition).

Compounds

Many organic compounds exist in optically active forms, i.e. they havethe ability to rotate the plane of plane polarized light. In describingan optically active compound, the prefixes R and S are used to denotethe absolute configuration of the molecule about its chiral center(s).For a given chemical structure, these compounds, called stereoisomers,are identical except that they are mirror images of one another. Aspecific stereoisomer may also be referred to as an enantiomer, and amixture of such isomers is often called an enantiomeric or racemicmixture.

Stereochemical purity is of importance in the field of pharmaceuticals,where 8 of the 10 most prescribed drugs exhibit chirality. A case inpoint is provided by the S-enantiomer of the β-adrenergic blockingagent, propranolol, which is known to be 100 times more potent than theR-enantiomer.

A synthesis of G-1 is described in Org. Biomol. Chem., 2010, 8,2252-2259, which is hereby incorporated by reference, and depicted inScheme 1. A catalytic amount of Sc(OTf)₃ (0.492 g, 1.0 mmol) inanhydrous acetonitrile (2.0 cm³) was added to the mixture of6-bromopiperonal (2.30 g, 10.0 mmol), p-aminoacetophenone (1.30 g, 10.0mmol) and cyclopentadiene (3.30 g, 50.0 mmol) in acetonitrile (25 cm³).The reaction mixture was stirred at ambient temperature (˜23° C.) for2.0 h. The volatiles were removed in vacuo. The residue was purified bypreparative silica gel column chromatography using ethyl acetate-hexanes(10:90) to provide G-1 (4.03 g, 98%, d.r.=94:6) as a white solid. Theminor diastereomer was substantially removed by recrystallization toyield a racemic mixture of SRR G-1 and RSS G-1.

Example 1: Isolation of the SRR G-1 and RSS G-1 Enantiomers

Starting with a highly purified sample of G-1,(±)1-(4-(6-bromobenzo[d][1,3]dioxol-5-yl)-(3aS*,4R*,9bR*)-tetrahydro-3H-cyclopenta[c]quinolin-8-yl)ethan-1-one,(99.4% purity) purchased from Tocris Bioscience, the material wasdissolved in 90:10:0.1(v/v/v) methyl tert-butyl ether/ethanol/diethylamine and subjected to preparative chromatography using a column packedwith Chrialpak 1A resin. Elution was conducted with 90:10:0.1(v/v/v)methyl tert-butyl ether/ethanol/diethyl amine and the fractionscorresponding to each enantiomer were collected and concentered to asolid. The early eluting enantiomer was determined to be the SRR G-1enantiomer by single crystal x-ray structural analysis.

Example 2: SRR G-1 Polymorph Screen

Starting with SRR G-1 prepared according to Example 1, a polymorphscreening study was conducted analyzing the solids isolated from slurryof the solid, or from fast and slow evaporation and cooling of solutions(Table 1). Two crystal forms were identified, an anhydrous formdesignated Form A and mono dichloromethane solvate designated Form B. Onexposure to elevated temperature the Form B crystal form desolvates toform the Form C crystal form. Amorphous material was generated frompurified SRR G-1 by two different methods; quick evaporating a diethylether solution of SRR G-1 or rotary evaporating from a solution of adichloromethane solution of SRR G-1.

Single Crystal Structure Determination of SRR G-1 (Form B)

Starting with SRR G-1 prepared according to Example 1, a suitable singlecrystal was grown from dichlomethane solution and analyzed bysingle-crystal X-ray diffractometry. The structure was determinedsuccessfully.

A single crystal was generated from a solution of dichloromethane afteran evaporative step. A colorless plate having approximate dimensions of0.19×0.14×0.03 mm³, was mounted on a polymer loop in random orientation.Preliminary examination and data collection were performed on a RigakuSuperNova diffractometer, equipped with a copper anode microfocus sealedX-ray tube (Cu Kα λ=1.54184 Å) and a Dectris Pilatus3 R 200K hybridpixel array detector. Cell constants and an orientation matrix for datacollection were obtained from least-squares refinement using the settingangles of 6979 reflections in the range 3.4920°<θ<77.1910°. The spacegroup was determined by the program CRYSALISPRO to be P212121(international tables no. 19). The data were collected to a maximumdiffraction angle (2θ) of 155.132° at room temperature.

Frames were integrated with CRYSALISPRO. A total of 10119 reflectionswere collected, of which 4368 were unique. Lorentz and polarizationcorrections were applied to the data. The linear absorption coefficientis 5.144 mm⁻¹ for Cu Kα radiation. An empirical absorption correctionusing CRYSALISPRO was applied. Transmission coefficients ranged from0.676 to 1.000. Intensities of equivalent reflections were averaged. Theagreement factor for the averaging was 3.4% based on intensity.

The structure was solved by direct methods using SHELXT. The remainingatoms were located in succeeding difference Fourier syntheses. Thestructure was refined using SHELXL-2014. Hydrogen atoms on SRR G-1 wererefined independently. The dichloromethane hydrogen atoms were includedin the refinement but restrained to ride on the atom to which they arebonded. The structure was refined in full-matrix least-squares byminimizing the function:

Σw(|F _(o)|² −|F _(c)|²)²

where the weight, w, is defined as 1/[σ²(Fo2)+(0.0464P)²+(0.1905P)],where P=(Fo2+2Fc2)/3. Scattering factors were taken from the“International Tables for Crystallography”. Of the 4368 reflections usedin the refinements, only the reflections with intensities larger thantwice their uncertainty [I>2σ(I)], 4071, were used in calculating thefit residual, R. The final cycle of refinement included 334 variableparameters, 0 restraints, and converged with respective unweighted andweighted agreement factors of:

R=|F _(o) −F _(c) |/ΣF _(o)=0.0348

R _(x)=√{square root over ((Σw(F _(o) ² −F _(c) ²)² /Σw(F_(o))²))}=0.0905

The standard deviation of an observation of unit weight (goodness offit) was 1.07. The highest peak in the final difference Fourier had anelectron density of 0.398 e/Å³. The minimum negative peak had a value of−0.438 e/Å³.

Calculated X-ray Powder Diffraction (XRPD) Pattern. A calculated XRPDpattern was generated for Cu radiation using MERCURY and the atomiccoordinates, space group, and unit cell parameters from the singlecrystal structure. Atomic Displacement Ellipsoid and Packing Diagrams.The atomic displacement ellipsoid diagram was prepared using MERCURY.Atoms are represented by 50% probability anisotropic thermal ellipsoids.Packing diagrams and additional figures were generated with MERCURY.Hydrogen bonding is represented as dashed lines. Assessment of chiralcenters was performed with PLATON. Absolute configuration is evaluatedusing the specification of molecular chirality rules.

The crystal system is orthorhombic and the space group is P2₁2₁2₁. Thecell parameters and calculated volume are: a=6.43156(10) Å, b=13.0752(2)Å, c=25.2941(4) Å, α=90°, β=90°, γ=90°, V=2127.09(6) Λ³. Standarduncertainty is written in crystallographic parenthesis notation, e.g.0.123(4) is equivalent to 0.123±0.004. The formula weight is 497.20 gmol⁻¹ with Z=4, resulting in a calculated density of 1.553 g cm⁻³.Further details of the crystal data and crystallographic data collectionparameters are summarized in Table 2. The quality of the structureobtained is high, as indicated by the fit residual, R, of 0.0348(3.48%). R-factors in the range 2%-6% are quoted to be the most reliablydetermined structures.

An atomic displacement ellipsoid drawing of SSR G-1 dichloromethanesolvate is shown in FIG. 1. The molecule observed in the asymmetric unitof the single crystal structure is consistent with the proposedmolecular structure of the SSR enantiomer. The asymmetric unit shown inFIG. 1 contains one SSR G-1 molecule and one dichloromethane molecule.

Packing diagrams viewed along the a, b, and c crystallographic axes areshown in FIGS. 2-4 respectively. Hydrogen bonding from the amine to thecarbonyl on adjacent molecules results in a one dimensional hydrogenbond network along the b axis, shown in FIG. 5.

The absolute structure can be determined through an analysis ofanomalous X-ray scattering by the crystal. Anomalous scattering isassessed through the intensity differences between Friedel pairs. Forthe reflection data measured up to θ_(max) the Friedel coverage was 95%.A refined parameter x, known as the Flack parameter, encodes therelative abundance of the two components in an inversion twin. Thestructure contains a fraction 1-x of the model being refined, and x ofits inverse. Provided that a low standard uncertainty is obtained, theFlack parameter should be close to 0 if the solved structure is correct,and close to 1 if the inverse model is correct. The measured Flackparameter for the structure of SSR G-1 dichloromethane solvate shown inFIG. 1 is −0.018 with a standard uncertainty of 0.013, which indicatesstrong inversion-distinguishing power.

Additional information regarding the absolute structure can be assessedby applying Bayesian statistics to Bijvoet differences. This analysisprovides a series of probabilities for different hypotheses of theabsolute structure. This analysis results in the Hooft y parameter,which is interpreted in the same fashion as the Flack x parameter. Inaddition, this analysis results in three probabilities that the absolutestructure is either correct, incorrect or a racemic twin. For thecurrent data set the (Flack equivalent) Hoofty parameter is −0.020(11),the probability that the structure is correct is 1.000, and theprobability that the structure is either incorrect or a racemic twin areboth less than 10⁻²⁰⁰.

The absolute configuration is labeled in FIG. 6. This is consistent withthe configuration of SRR G-1.

FIG. 7 shows a calculated XRPD pattern of SRR G-1 dichloromethanesolvate, generated from the single crystal structure. The calculatedXRPD pattern is identical to that assigned to bulk samples identified asdisplaying the Form B XRPD pattern in the polymorph screening studysummarized in Table 1.

Starting with SRR G-1 prepared according to Example 1, a suitable singlecrystal of the Form A crystal form was grown from isopropanol solutionand analyzed by single-crystal X-ray diffractometry. The structure wasdetermined successfully. A single crystal x-ray analysis was conductedon a colorless plate having approximate dimensions of 0.203×0.137×0.033mm³, was mounted on a polymer loop in random orientation. Preliminaryexamination and data collection were performed on a Rigaku SuperNovadiffractometer, equipped with a copper anode microfocus sealed X-raytube (Cu Kα λ=1.54184 Å) and a Dectris Pilatus3 R 200K hybrid pixelarray detector. Cell constants and an orientation matrix for datacollection were obtained from least-squares refinement using the settingangles of 9009 reflections in the range 4.7640°<θ<77.3860°. The spacegroup was determined by the program CRYSALISPRO to be P2₁2₁2₁. The datawere collected to a maximum diffraction angle (2θ) of 155.264° at roomtemperature.

Frames were integrated with CRYSALISPRO. A total of 17299 reflectionswere collected, of which 7561 were unique. Lorentz and polarizationcorrections were applied to the data. The linear absorption coefficientis 3.206 mm⁻¹ for Cu Kα radiation. An empirical absorption correctionusing CRYSALISPRO was applied. Transmission coefficients ranged from0.733 to 1.000. Intensities of equivalent reflections were averaged. Theagreement factor for the averaging was 2.74% based on intensity.

The structure was solved by direct methods using SHELXT. The remainingatoms were located in succeeding difference Fourier syntheses. Thestructure was refined using SHELXL-2014. Hydrogen atoms were refinedindependently. The structure was refined in full-matrix least-squares byminimizing the function:

Σw(|F _(o)|² −|F _(c)|²)²

where the weight, w, is defined as 1/[σ²(F_(o) ²)+(0.0401P)²+(0.3205P)],where P=(F_(o) ²+2F_(c) ²)/3. Scattering factors were taken from the“International Tables for Crystallography”. Of the 7561 reflections usedin the refinements, only the reflections with intensities larger thantwice their uncertainty [I>2σ(I)], 6752, were used in calculating thefit residual, R. The final cycle of refinement included 613 variableparameters, 0 restraints, and converged with respective unweighted andweighted agreement factors of:

R=Σ|F _(o) −F _(c) |/ΣF _(o)=0.0325

R _(w)=√{square root over ((Σw(F _(o) ² −F _(c) ²)² /Σw(F _(o)²)²))}=0.0813

The standard deviation of an observation of unit weight (goodness offit) was 1.04. The highest peak in the final difference Fourier had anelectron density of 0.319 e/Å³. The minimum negative peak had a value of−0.454 e/Å³.

The crystal system is orthorhombic and the space group is P2₁2₁2₁. Thecell parameters and calculated volume are: a=6.50106(9) Å, b=17.3547(2)Å, c=32.6957(4) Å, α=90°, β=90°, γ=90°, V=3688.85(9) Å³.

Example 3: Form and Polymorph Data

SRR G-1 forms two distinctive polymorphs, Forms A and C; a solvate, FormB; as well as amorphous material. The XRPD patterns for the crystallineforms are compared in FIG. 10. Form B is a mono DCM solvate thatdesolvates to Form C upon exposure to elevated temperatures between 100and 120° C. Form C, the desolvate, exhibits a melt onset near 129° C.Form A is the thermodynamically stable form at all temperatures(monotropically related to Form C) and exhibits a melt onset near 178°C. Amorphous material is not physically stable and crystallizes to FormA upon exposure to either elevated temperature or humidity. The formsare discussed in more detail in subsequent sections below.

The thermograms for Form B are shown in FIG. 15. The ThermogravametricAnalysis (TGA) curve exhibits a weight loss of approximately 15.3% up to177° C., consistent with the volatilization of 0.9 mol/mol DCM. The lossoccurs concurrently with a desolvation endotherm (max 104° C.) andrecrystallization exotherm (max 140° C.) in the DSC thermogram. Therecrystallized material exhibits a final melt endotherm with an onsetnear 176° C. consistent with the melt of Form A. The DSC thermogram forthe mixture of Forms B and C is provided in FIG. 16. The mixtureexhibits a desolvation endotherm (max 101° C.) followed by the meltendotherm (onset near 128° C.) of the desolvated form, Form C.

The physical stability of Form B was investigated. Complete desolvationto Form C occurred upon exposure to 120° C. Almost complete desolvationwas evident upon exposure to 90 to 100° C. for 25 minutes. Vacuum at 70°C. (or below) was not sufficient for desolvation to occur.

Crystalline Form C

Form C is a desolvate with a melt onset near 129° C. generated throughthe desolvation of Form B (mono DCM solvate).

The XRPD pattern of Form C was successfully indexed, suggesting it iscomposed of a single crystalline phase (FIG. 17). Assuming the chemicalcomposition is correct, it has an orthorhombic unit cell containing fourmolecules of SRR G-1. Consequently, the formula unit volume of 462.88 Å³calculated from the indexing results would be consistent with ananhydrous form with a calculated density of 1.479 g cm⁻³.

The differential scanning calorimetry (DSC) thermogram for Form C isshown in FIG. 18. The DSC exhibits a single endotherm with an onset near129° C. (23 J/g). The event was visually confirmed on a hot plate as amelt.

Amorphous

The physical stability of amorphous material generated from purified SRRG-1 was investigated. Amorphous material crystallized to Form A uponexposure to either elevated temperature (within 4 days at 60° C.) orhumidity (within 12 days at 75% RH). This indicates that amorphousmaterial is not stable at the conditions evaluated.

Relative Thermodynamic Stability of the Crystalline Forms

Phase transitions of solids can be thermodynamically reversible orirreversible. Crystalline forms which transform reversibly at a specifictransition temperature are called enantiotropic polymorphs. If thecrystalline forms are not interconvertible under these conditions, thesystem is monotropic (one thermodynamically stable form). Several ruleshelp predict the relative thermodynamic stability of polymorphs andwhether the relationship between the polymorphs is enantiotropic ormonotropic. The density and heat of fusion rules, justified on astatistical mechanical basis, are used here for guidance of monotropy orenantiotropy.

The density rule, which is based on Kitaigorodskii's principle ofclosest packing for molecular crystals, states that, for anon-hydrogen-bonded system at absolute zero, the most stable polymorphwill have the highest density, because of stronger intermolecular vander Waals interactions. Thus, according to this rule, the crystalstructure with most efficient packing will also have the lowest freeenergy. This assumes that hydrogen bonding (long range effect) is not amajor parameter in crystal packing. The densities determined from thesingle crystal structure of Form A and indexing results of Form Csuggest that, at absolute zero, Form A is more stable than Form C (1.485and 1.479 g cm⁻³, respectively).

The melt onsets and heats of fusion, obtained from calorimetry data, areuseful to estimate the relative physical stabilities of the forms at alltemperatures (FIGS. 11 and 18). From the heat of fusion rule, two formsare enantiotropic if the higher melting form has the lower heat offusion, otherwise they are monotropic. The density and heat of fusionrules for this system appear consistent with a monotropic relationship.

Interconversion experiments were performed to experimentally test thethermodynamic relationship between Forms A and C. Interconversion orcompetitive slurry experiments are a solution-mediated process thatprovides a pathway for the less soluble (more stable) crystal to grow atthe expense of the more soluble crystal form. Outside the formation of asolvate or degradation, the resulting more stable polymorph from aninterconversion experiment is independent of the solvent used becausethe more thermodynamically stable polymorph has a lower energy andtherefore lower solubility. The choice of solvent affects the kineticsof polymorph conversion and not the thermodynamic relationship betweenpolymorphic forms. Saturated solutions were generated and then added tomixtures composed of approximately equivalent quantities of the twopolymorphs. The samples were slurried for nine days and the solidsharvested and analyzed by XRPD. The results of the interconversionstudies confirm Form A is thermodynamically more stable at roomtemperature relative to Form C. The experimentally determined relativestability at room temperature, the suggested relative stability atabsolute zero based on the density rule, and monotropism as determinedby the heat of fusion rule all imply that Form A is more stable thanForm C at any temperature.

The pKa, Log D_(7.4) and Log P of compound SRR G-1 were predicted byMarvinSketch 5.6.0.2, the results showed the pKa of SRR G-1 is 1.90(base, pH range of 0˜14), Log D_(7.4) is 5.32 and Log P is 5.32. A pKatitration test showed that no pKa value was observed in the range of3˜11, which was consistent with the prediction result. Log D_(7.4) wasmeasured with the solvent systems of pH 7.4 phosphate buffer andn-octanol by shake-flask method. Detailed results of Log D_(7.4) and LogP were displayed in Table 16. Since the solubility of SRR G-1 freebasein aqueous phase was lower than <0.82 μg/mL, the Log D_(7.4) wasdetermined to be >3.22 and Log P was >3.22 considering the small pKavalue.

Instrumental Techniques Differential Scanning Calorimetry (DSC)

DSC was performed using a Mettler-Toledo DSC3+ or DSC822e differentialscanning calorimeter. A tau lag adjustment is performed with indium,tin, and zinc. The temperature and enthalpy are adjusted with octane,phenyl salicylate, indium, tin and zinc. The adjustment is then verifiedwith octane, phenyl salicylate, indium, tin, and zinc. The sample wasplaced into a hermetically sealed aluminum DSC pan, and the weight wasaccurately recorded. The pan was then inserted into the DSC cell. Aweighed aluminum pan configured as the sample pan was placed on thereference side of the cell. The pan lid was pierced prior to sampleanalysis. Samples were analyzed from −30° C. to 250° C. @ 10°/min. Thecyclic DSC method heated from −30° C. to 100° C., returned to −30° C.,then heated to 250° C. at 10°/min.

Dynamic Vapor Sorption/Desorption (DVS)

Moisture sorption/desorption data were collected on a VTI SGA-100 VaporSorption Analyzer. NaCl and PVP were used as calibration standards.Samples were not dried prior to analysis. Sorption and desorption datawere collected over a range from 5% to 95% RH at 10% RH increments undera nitrogen purge. The equilibrium criterion used for analysis was lessthan 0.0100% weight change in 5 minutes with a maximum equilibrationtime of 3 hours. Data were not corrected for the initial moisturecontent of the samples.

Thermogravimetric Analysis (TGA)

Thermogravimetric analysis was performed using a Mettler-Toledo TGA/DSC3analyzer. Temperature and enthalpy adjustments were performed usingindium, tin, and zinc, and then verified with indium. The balance wasverified with calcium oxalate. The sample was placed in an open aluminumpan. The pan was hermetically sealed, the lid pierced, then insertedinto the TG furnace. A weighed aluminum pan configured as the sample panwas placed on the reference platform. The furnace was heated undernitrogen. Each sample was heated from ambient temperature to 350° C. at10° C./min. Although thermograms are plotted by reference temperature(x-axis), results are reported according to sample temperatures.

X-Ray Powder Diffraction (XRPD)

XRPD pattern was collected with a PANalytical X′Pert PRO MPD orPANalytical Empyrean diffractometer using an incident beam of Curadiation produced using a long, fine-focus source. An ellipticallygraded multilayer mirror was used to focus Cu Kα X-rays through thespecimen and onto the detector. Prior to the analysis, a siliconspecimen (NIST SRM 640e) was analyzed to verify the observed position ofthe Si 111 peak is consistent with the NIST-certified position. Aspecimen of the sample was sandwiched between 3-μm-thick films andanalyzed in transmission geometry. A beam-stop, short antiscatterextension, and antiscatter knife edge were used to minimize thebackground generated by air. Soller slits for the incident anddiffracted beams were used to minimize broadening and asymmetry fromaxial divergence. Diffraction patterns were collected using a scanningposition-sensitive detector (X′Celerator) located 240 mm from thespecimen and Data Collector software v. 2.2b or 5.5.

Scale-up andcharacterization of the salts are described in more detail in subsequentsections below.

SRR G-1 Besylate Form A

SRR G-1 Besylate Form A is an anhydrous 1:1 stoichiometric salt with anapparent melt onset near 186° C. Disproportionation of the salt in waterwas not evident.

The single-crystal structure of SRR G-1 Besylate Form A was determinedsuccessfully. Thus colorless needle having approximate dimensions of0.23×0.09×0.04 mm³, was mounted on a polymer loop in random orientation.Preliminary examination and data collection were performed on a RigakuSuperNova diffractometer, equipped with a copper anode microfocus sealedX-ray tube (Cu Kα λ=1.54184 Å) and a Dectris Pilatus3 R 200K hybridpixel array detector. Cell constants and an orientation matrix for datacollection were obtained from least-squares refinement using the settingangles of 13177 reflections in the range 4.2570°<θ<77.0580°. The spacegroup was determined by the program CRYSALISPRO to be P2₁. The data werecollected to a maximum diffraction angle (2θ) of 155.242° at roomtemperature.

Frames were integrated with CRYSALISPRO. A total of 26894 reflectionswere collected, of which 10520 were unique. Lorentz and polarizationcorrections were applied to the data. The linear absorption coefficientis 3.323 mm⁻¹ for Cu Kα radiation. An empirical absorption correctionusing CRYSALISPRO was applied. Transmission coefficients ranged from0.837 to 1.000. Intensities of equivalent reflections were averaged. Theagreement factor for the averaging was 3.3% based on intensity.

The structure was solved by direct methods using SHELXT. The remainingatoms were located in succeeding difference Fourier syntheses. Thestructure was refined using SHELXL-2014. Hydrogen atoms were refinedindependently. The structure was refined in full-matrix least-squares byminimizing the function:

Σw(|F _(o)|² −|F _(c)|²)²

where the weight, w, is defined as 1/[σ²(F_(o) ²)+(0.0401P)²+(0.3205P)],where P=(F_(o) ²+2F_(c) ²)/3. Scattering factors were taken from the“International Tables for Crystallography”. Of the 10520 reflectionsused in the refinements, only the reflections with intensities largerthan twice their uncertainty [I>2σ(I)], 9411, were used in calculatingthe fit residual, R. The final cycle of refinement included 723 variableparameters, 1 restraint, and converged with respective unweighted andweighted agreement factors of:

R=Σ|F _(o) −F _(c) |/ΣF _(o)=0.0348

R _(w)=√{square root over ((Σw(F _(o) ² −F _(c) ²)² /Σw(F _(o)²)²))}=0.0874

The standard deviation of an observation of unit weight (goodness offit) was 1.05. The highest peak in the final difference Fourier had anelectron density of 0.311 e/Å³. The minimum negative peak had a value of−0.280 e/Å³.

The crystal system is monoclinic and the space group is P2₁. The cellparameters and calculated volume are: a=14.1207(3) Å, b=8.74139(11) Å,c=21.5361(4) Å, α=90°, β=106.1889(19)°, γ=90°, V=2552.89(8) Å³. Theformula weight is 570.44 g mol⁻¹ with Z=4, resulting in a calculateddensity of 1.484 g cm⁻³. Further details of the crystal data andcrystallographic data collection parameters are summarized in Table 17.An atomic displacement ellipsoid drawing of Besylate Form A is shown inFIG. 26. The asymmetric unit shown contains two SRR G-1 cations and twobesylate anions. The —SO₃ moiety was modeled with rotational disorder onboth anions. A calculated XRPD pattern generated for Cu radiation usingMERCURY and the atomic coordinates, space group, and unit cellparameters from the single crystal structure is provided in FIG. 27 andcompared to the experimental pattern.

The solution ¹H NMR spectrum is consistent with a 1:1 stoichiometricsalt of SRR G-1 and benzenesulfonic acid. Residual solvent is notevident, consistent with an unsolvated form.

Thermograms of SRR G-1 Besylate Form A are provided in FIG. 28.Negligible weight loss up to 186° C. is evident by TGA, consistent withan anhydrous form. The DSC exhibits a sharp endotherm with an onset near186° C. The event is likely due to a melt concurrent with decomposition.A small endotherm near 164° C. is also evident. The nature of thisendotherm is unknown.

A molar equivalent, 0.50 g, of benzenesulfonic acidmonohydrate was added to a vessel containing 1.17 g of SRR G-1 freebaseForm A. In addition, a small quantity of SRR G-1 Besylate Form A wasadded as seeds. Ethyl acetate, 7 mL, was added and followed bysonication. A predominant portion of the solids dissolved, resulting ina yellow solution, but was immediately followed by precipitation ofwhite solids. An additional 3 mL of ethyl acetate was added tofacilitate slurry transfer and filtration. The solids were recovered byvacuum filtration and rinsed with 4 mL of ethyl acetate followed byvacuum at room temperature overnight. Approximately 0.99 grams of SRRG-1 Besylate Form A was obtained.

The solution ¹H NMR spectrum is consistent with a 1:1 stoichiometricsalt of SRR G-1 and naphthalene-2-sulfonic acid. Residual solvent is notevident, consistent with an unsolvated form.

Thermograms for SRR G-1 Napsylate Form A are provided in FIG. 33.Approximately 0.5% weight loss up to 193° C. is evident by TGA. Themajority of the loss occurs above ˜100° C. Because organic solvent wasnot observed by NMR, discussed above, it is assumed the loss is due tothe volatilization of approximately 0.2 mol/mol water. This suggeststhat the salt may exhibit limited hygroscopicity. The DSC exhibits asharp endotherm with an onset near 194° C. The event is likely due to amelt concurrent with decomposition.

The possibility of disproportionation in water was investigated. SRR G-1Napsylate Form A was slurried in water for 5 days. The excess solidswere recovered and reanalyzed by XRPD for evidence of freebase ornaphthalene-2-sulfonic acid. The recovered material was freebase Form A,indicating that disproportionation occurred under the conditionevaluated.

The following describes a 600-mg scale procedure for generating SRR G-1Napsylate Form A. Seeds of SRR G-1 Napsylate Form A and a molarequivalent, 0.39 g, of naphthalene-2-sulfonic acid was added to a vesselcontaining a suspension of 0.73 g of SRR G-1 freebase Form A and 9 mL ofethyl acetate. The yellow suspension with a small amount of undissolvedsolids was sonicated and a white precipitation occurred. The slurry wassonicated for an additional ˜5 minutes and the solids were thenrecovered by vacuum filtration, rinsed with 2 mL of ethyl acetate, anddried under vacuum at room temperature overnight. Approximately 0.63grams of SRR G-1 Napsylate Form A was obtained.
